摘要: 目的 研究重庆市低出生体重儿的影响因素,为预防和降低全市低出生体重发生率提供理论依据。方法 采用1∶1病例对照研究方法选取重庆市6所妇幼保健院住院分娩的326名低出生体重儿和同期住院分娩的326名正常新生儿作为研究对象,利用问卷进行调查,采用单因素和多因素条件Logistic回归分析所获资料。结果 低出生体重儿的发生可能与母亲一般情况(孕前BMI、受教育程度、家庭平均月收入等)、孕期情况(单胎、产前检查、妊娠期高血压疾病等)、生活习惯(吸烟、饮酒、被动吸烟等)和膳食营养(服用多种维生素片、食用鱼禽肉类、食用海产植物类等)有关。多因素分析结果显示,家庭平均月收入、单胎、孕期增重和产前检查是低出生体重儿的主要保护因素,妊娠期贫血是影响低出生体重儿的主要危险因素。结论 低出生体重儿的发生受多方面因素共同作用的影响,应采取综合措施降低低出生体重儿的发生率。
